FIELD OF THE INVENTION

The present invention relates to the field of wave energy power. In particular, the present invention relates to a desalination and electricity generation system. More particularly, the present invention relates to the exploitation of wave energy for desalination and/or electricity generation. Even more particularly, the present invention relates to desalination using a reverse-osmosis process.

BACKGROUND OF THE INVENTION

Salt water desalination systems have been in use for many years. Salt water can be desalinated to produce fresh water through a variety of processes, but typically desalination systems utilize reverse osmosis to separate fresh water from salt water.

Reverse osmosis, though effective, requires a significant amount of energy to generate the amount of pressure necessary for the process to work efficiently. Fossil fuel energy systems typically power desalination systems and correspondingly these systems generate pollution. In addition, fossil fuels are a finite resource as well as expensive, and therefore are not suitable for poor nations desiring a method of generating fresh water.

The energy generated by the rise and fall of waves has been studied for a long time. However, wave power has not been effectively utilized to run a reverse osmosis desalination system. Since most desalination systems use reverse osmosis, the pressures necessary for the system to work efficiently are too power-demanding for this type of energy system. Additionally, other methods for desalinating water have not effectively utilized wave power.

The need for fresh water in the world continues to increase. However, the desalination of the ocean and other salt water bodies remains underdeveloped due to technology limitations. Reverse osmosis demands considerable electrical energy and is therefore too costly. The energy systems conventionally utilized pollute the environment and drain limited finite fossil fuel resources.

In order to provide a pollution free, cost efficient solution, utilizing wave energy, to result in a wave powered desalination and/or electricity system, the system would be required to substantially depart from the conventional concepts and designs of the prior art.

It is would therefore be desirable to provide a system for extracting wave and water stream energies effectively in order to convert them into the required pressures for desalination.

SUMMARY OF THE INVENTION

Accordingly, it is a principle object of the invention to provide a system for extracting wave and water stream energies effectively in order to convert them into electricity.

It is still a further object of the present invention to provide a system for extracting wave and water stream energies that requires little or no daily intervention in order to operate properly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention relates to seawater desalination powered by wave energy, for extracting fresh water from seawater by means of a Reverse-Osmosis (RO) process using plastic-membrane filters. Additionally, electrical power may be generated for commercial use. The powering energies are to be supplied by sea waves and tides that are renewable, instead of fossil sourced fuels that largely contribute to the excess atmospheric CO₂ levels.

A preferred embodiment of the seawater collection system of the present invention is shown schematically in FIG. 1 in a block diagram, and designated generally by reference numeral (100). System (100) comprises an intake portion (110) for directing the seawater waves (10) to a wave augmentation portion (120). Wave augmentation portion (120) converts the kinetic energy of seawater waves (10) to potential energy. A wave energy discriminator (130) is aligned at its first end with wave augmentation portion (120), for differentiating between kinetic energy levels of the seawater. System (100) further comprises a low pressure seawater collector (140), and a low pressure to high pressure converter (150) for enabling desalination. An optional negative discharge compartment (170) is additionally included in the present invention, as described further herein below.

FIGS. 2-8 show the various components of system (100) of the first embodiment in schematic detail. With reference to FIG. 2, a front perspective view of intake portion (110) is shown comprising a channel facing the sea, having longitudinal side walls (112) for guiding waves (10) coming from different directions, to wave augmentation portion (120). Preferably, intake portion (110) has more than one channel. Each wall (112) extends preferably 25-30 meters outwards towards the sea. Intake portion (110) (comprising, preferably several channels) preferably extends 50-60 meters across the sea surface. Each wall (112) is fixed to the sea floor (not shown) and preferably extends from the sea floor at least 5 meters above the highest sea level along the length of wall (112).

Referring to FIG. 3, a side view of wave augmentation portion (120) is shown with the intake portion not shown for reasons of clarity, comprising an upwardly inclined adjustable ramp (122) having a sea side (A) for receiving the seawater, and a shore side (B) for discriminating the wave energy (as described further herein below). Ramp (122) is comprised, in this embodiment, of three essentially similar sections (124 a-c), although a fewer or greater number of sections may be present in alternative embodiments. Each section (124 a-c) has a slope, which is selectively changeable by a control mechanism (126) such as an electrical motor, shown in the figure affixed to the lower end of each section (124 a-c), although the particular location of mechanism (126) may be different according to design, mechanical and other considerations.

Control mechanism (126) is preferably remotely and automatically controlled, and comprises sensors (not shown) for detecting desired parameters such as sea conditions, weather conditions, etc. The desired parameters are transferred to a remote location for enabling automatic control of sections (124 a-c). Alternatively, control mechanism (126) may be operated manually according to the same desired parameters.

Waves (10) are shown in FIG. 3 directed from the intake portion (see FIG. 2) moving towards and up ramp (122). As seen, the amount of seawater that reaches the lower section (124 a) of ramp (122) is greater than that which reaches the upper section (124 c) of ramp (122). Ramp (122) augments the height of the seawater, and in doing so converts the kinetic energy of the seawater into potential energy.

According to a preferred embodiment, ramp (122) is 25-30 meters across the sea surface, preferably essentially corresponding to the distance across the sea surface of the proximal ends of the walls of the intake portion (not shown in this figure). Ramp (122) reaches preferably 10-15 meters in height, that is, above the sea level.

In FIG. 4, wave energy discriminator (130) is shown comprising an array of seawater transferring ducts (132) for transferring seawater to a low pressure seawater collector (FIG. 6). Wave energy discriminator (130) is located above the upper section (124 c) of ramp (122), on the shore side (B) of ramp (122). Each duct (132) extends the transverse length of ramp (i.e. 25-30 meters) as well as outwards, orthogonally away from the sea side (A) (See FIG. 3) of ramp (122), preferably a distance of 5 meters.

Each duct (132) comprises an inlet (134), which opens towards ramp (122), and an outlet (136), which opens at the low pressure seawater collector (see FIG. 6). Each inlet (134) comprises a cover (138) for selectively allowing and preventing seawater from entering respective ducts (132) FIGS. 5 a and 5 b show one duct (132) enlarged for illustrative purposes, where the cover (138), in the form of a pivotable flap is shown in the closed (FIG. 5 a) and open (FIG. 5 b) positions.

Referring to FIG. 5 a, as the seawater travels up the ramp and up the discriminator, as indicated by arrow (131 a), the seawater applies a force on flap (138), thereby maintaining duct (132) in a closed position. When the seawater travels back down the discriminator and ramp, as indicated by arrow (131 b), the seawater contacts the upper edge of flap (138), thereby causing flap (138) to open by pivoting about axis (139). Preferably, the upper edge of flap (138) comprises an outwardly extending lip (not shown) that catches the seawater on its way down. While duct (132) is open, the seawater enters through inlet (134), as indicated by arrow (131 c), and travels therethrough towards the low pressure seawater collector.

Wave energy discriminator (130) essentially divides the seawater that travels up the ramp, into distinct levels of potential energy, such that the seawater that enters the upper (higher) ducts store a greater amount of potential energy than does the seawater that enters the lower ducts.

Wave augmentation portion (120) and wave energy discriminator (130) are preferably situated in an adjustably fixed position above the surface of the sea, wherein the precise positions are set via a computer control. In one embodiment, wave augmentation portion (120) and wave energy discriminator (130) float on the sea, and have an anchor to fix their position. In an alternative embodiment, wave augmentation portion (120) and wave energy discriminator (130) are fixed to the floor of the sea.

FIG. 6 shows low pressure seawater collector (140) aligned with the second end of wave energy discriminator (130) (not shown), comprised of a plurality of seawater first-receptacles (142) for receiving seawater from the ducts (132) (not shown), as indicated by arrow (131 c). First-receptacles (142) are arranged along a first vertical conveyer (143) having an upper and lower rotating wheel (or, pulley) (144 a), (144 b), respectively. Seawater passes from ducts (132) to each of the respective receptacles (142). The gravitational force created by the filled receptacles (142) causes each receptacle (142) to shift downwards along conveyer (143) as shown by arrows (141), which simultaneously causes each rotating wheel (144 a), (144 b) to rotate about its rotational axis. As understood from the figure, when each filled receptacle (142) passes around lower wheel (144 b), receptacle (142) rotates essentially 180 degrees, thereby unloading the seawater back into the sea.

Optionally, seawater collection system (100) of the present invention further comprises a negative discharge compartment (170), shown schematically in FIG. 1. Referring to FIG. 8, compartment (170) is disposed below the surface of the sea, beneath receptacles (142). In their normal/initial position, covers (172) are closed. The lower crest of a wave traveling towards system (100) causes covers (172) to open and allow seawater to enter the inlets (174) that are normally closed by covers (172). When this cycle is repeated, the seawater contained in compartment (170) is discharged through outlet (176). The discharged seawater creates an underwater force that provides an additional drive to conveyer (143) (that is, in addition to the gravitational pull of receptacles (142)).

Referring back to FIG. 6, in the present embodiment, the lower wheel (144 b) is coupled with a second vertical conveyer (145). Second vertical conveyer (145) comprises a plurality of second receptacles (147) for receiving seawater directly from the sea, and raising the seawater to the upper end of second vertical conveyer (145). Second receptacles (147) typically have a smaller volume than first receptacles (142). At the upper end of second vertical conveyer (145), second receptacles (147) are emptied into a low pressure seawater tank (149).

Second vertical conveyer (145) elevates the seawater higher than first vertical conveyer (143). For instance, second vertical conveyer (145), an in turn tank (149) is preferably elevated to a height of 25 meters, whereas first vertical conveyer elevates the seawater to 3 meters. According to a preferred embodiment, water pressure at tank (149) is 2-2.5 bar.

As mentioned herein above, in order to enable utilization of the seawater for RO desalination, the water pressure is required to be 50-70 bar. To that end, the present invention further comprises a low to high pressure converter (150), shown in a side view, schematically in FIG. 7.

It is understood that the relative size of conveyer (143) to conveyer (145) is not shown to scale. Moreover, a greater or fewer amount of receptacles may be present along conveyers (143) and (145), depending on design and other considerations.

As seen in FIG. 7, low pressure to high pressure converter (150) comprises a large cylinder (154), which receives at its upper end, the low pressure seawater contained in tank (149), via a first seawater transfer pipe (152). A small cylinder (158), disposed within large cylinder (154), receives low pressure seawater contained in tank (149), via a second seawater transfer pipe (156), at the lower end of small cylinder (158). A large piston (160), for shifting within large cylinder (154), and a small piston (162), for shifting within small cylinder (158) are joined by a shaft (164), such that cylinders (154), (158) are raised and lowered concomitantly. A seawater exit pipe (166) transfers high pressure seawater from small cylinder (158) to a desalination system (not shown).

In operation of low pressure to high pressure converter (150), in the initial stage of the converter cycle, first pipe valve (161) and exit valve (165) are closed, and second pipe valve (163) is open to allow seawater to enter chamber (C) in small cylinder (158). The increase in pressure in chamber (C) forces piston (162) upwards, and thereby, piston (160), upwards, toward the upper surface of large cylinder (154). Ventilation valves (not shown) allow excess air and seawater present in chamber (D) of large cylinder (154) to exit therefrom.

In the second stage, second pipe valve (163) and ventilation valves are closed, and first pipe valve (161) is open to allow seawater from tank (149) to fill chamber (D). The force of the seawater entering chamber (D) pushes large piston (160) downwards, and thereby, piston (162) downwards, towards the lower surface of small cylinder (158). Simultaneously, exit valve (165) is open, and high pressure water exits low to high pressure converter (150) to the desalination system (not shown).

The pressure of the seawater that exits the small cylinder is between 50-75 bar. This pressure increase results from the inverse proportion of the areas of large piston (160) to small piston (162).

The cycle returns to the initial stage, wherein first pipe valve (161) and exit valve (165) are closed, and second pipe valve (163) is open to allow seawater to enter chamber (C) in small cylinder (158).

In some embodiments (not shown in the figures) a third or alternative transfer pipe transfers seawater from tank (149) to a water turbine system for generating electrical power. Preferably, the generated power is at least the amount of power required for powering the desalination system.

The present invention may be utilized with a conventional RO desalination system, which requires 50-75 bar seawater. Such a system would include RO filter banks, which comprise a pressure recovery subsystem for higher efficiency, a post filter and a purified water outlet.

It is understood that the present invention may be utilized as a single system or may be combines with additional seawater collection systems of the present invention in order to maintain maximum efficiency for desalination and/or energy generation.

A second embodiment of the present invention is shown schematically in FIG. 9, showing the seawater collection system (200) in a side view, and schematically in FIG. 10, showing a top view of the fluid spoiler system (280). The second embodiment comprises all of the essential features and components of system (100) of the first embodiment, mutatis mutandis, with the following differences.

According to the second embodiment, seawater collection system (200) comprises a fluid spoiler system (280) for disrupting the flow of the seawater to increase the amount of turbulent flow as well as velocity, thereby converting the potential energy of the sea waves to kinetic energy. As seen in FIG. 9, the underwater spoiler system (280) is positioned beneath the water, above the sea bed (2) and in front of wave augmentation portion (220) as well as in front of the intake portion (not shown in this figure). Elevated waves (11) are schematically shown raised above wave augmentation portion (220).

Referring to FIG. 10, a longitudinal row of spoilers (281) and (282) is positioned in front of each transversal end of the intake portion (not shown). A matrix of lagrangian sensors (284) is positioned between the two rows of spoilers (281) and (282) for determining the velocity of the seawater as a function of the x, y, z coordinates. A control algorithm provided by the control software transmits the sensor data to a data processor (not shown) which acts as a control optimizer for adjusting the position of each spoiler (281 a), (281 b), (281 c) and (282 a), (282 b), (282 c). Spoilers (281 a), (281 b), (281 c) and (282 a), (282 b), (282 c) are positioned according to the direction of the sea waves (10), wherein, for instance, the amplitude of a first portion (10 a) of sea wave (10) is in a positive direction (peak) and the amplitude of a second portion (lob) of sea wave (10) is in a negative direction (trough).

It should be noted that although three spoilers are illustrated in each of the rows of spoilers, fewer or more spoilers may be present according to the present invention, depending on design, mechanical and other considerations.

A control mechanism (290) is coupled with each spoiler (281 a), (281 b), (281 c) and (282 a), (282 b), (282 c) similar to that described herein above with regards to the sections of the wave augmentation portion. Control mechanism (290) may be situated, for instance, at an end of a spoiler (281 a), (281 b), (281 c) and (282 a), (282 b), (282 c) or in the middle, as shown in the figures. Control mechanism (290) is preferably remotely and automatically controlled, or alternatively, control mechanism (126) may be operated manually.

A third embodiment of the present invention is shown schematically in FIG. 11, showing a schematic top view of the seawater collection system (300). The third embodiment comprises all of the essential features and components of systems (200) and (300) of the first and second embodiments, mutatis mutandis, with the following differences.

According to the third embodiment, system (300) further comprises a phase entry system (390) comprising a pair of gates (391), (392) for enabling an alternating movement of the seawater waves towards wave augmentation portion (320). Gates (391), (392) are located between intake portion (310) and wave augmentation portion (320). Gates (391), (392) selectively alternate between an open position and a closed position, such that when the first gate (391) is open, the second gate (392) is closed, and visa versa. System (300) is divided into two longitudinal sections, thereby forming two wave augmentation sections (320 a), (320 b), two wave energy discriminators (330 a), (330 b), two sets of low pressure seawater collectors (340 a), (340 b), etc.

In a first sequence the seawater (10) passes from intake portion (310) through the open gate (391), and travels through system (300) as described herein above regarding the first embodiment. After the seawater passes through system (300), the seawater returns to the sea. Preferably, the “used” seawater (14) travels around system (300), as indicated in FIG. 11 by arrow (12).

In a second sequence “used” seawater (14) enters intake portion (310), second gate (392) is open and first gate (391) is closed. “Used” seawater (14) passes from intake portion (310) through the open gate (391), and travels through system (300) as described above.

One cycle of system (300) of the third embodiment is comprised of a first and second sequence.
